Changelog entry (a user-readable short description of the changes that goes to CHANGELOG.md):
Convert history file from readline format to replxx format

Detailed description / Documentation draft:
replxx requires each history line to prepended with time line:

### YYYY-MM-DD HH:MM:SS.SSS
select 1

And w/o those service lines it will load all lines from history file as
one history line for suggestion. And if there are lots of lines in file it
will take lots of time (getline() + tons of reallocations).

Thank you!

LGTM. The code is dirty but we don't need anything good here.

Sorry, this PR contains a bug.

Fresh installation:

ubuntu@ip-172-31-43-234:~$ clickhouse-client 
ClickHouse client version 21.9.1.7510 (official build).
Connecting to localhost:9000 as user default.
Connected to ClickHouse server version 21.9.1 revision 54449.


Cannot read from /home/ubuntu/.clickhouse-client-history (for conversion): errno: 2, strerror: No such file or directory
ip-172-31-43-234.us-east-2.compute.internal :)

I will revert.
